What is the .NET equivalent of "ProducesResponseType" from Net Core?

Question

I have to do a "backward" from an API made with NET CORE to .NET

I'm facing a problem changing [ProducesResponseType] from Net Core in a valid equivalent of .NET

I have for example this code:

[ApiExplorerSettings(GroupName = "groupName")]
[ProducesResponseType(typeof(something), StatusCodes.Status200OK)]
[ProducesResponseType(typeof(void), StatusCodes.Status400BadRequest)]
[ProducesResponseType(typeof(void), StatusCodes.Status401Unauthorized)]
[ProducesResponseType(typeof(void), StatusCodes.Status500InternalServerError)]
[HttpPost("thing", Name = "creatingThisThing")]
public async Task<IHttpActionResult> PostThing([FromBody]dynamic value)
        {
           /// Other Stuff

I understand I can avoid using the group name and I can adapt the route like this:

[HttpPost]
[Route("", Name = "creatingThisThing")]
/// etc

But I'd like to know what can I use to "replace" the previously mentioned.

Hope I was clear enough.

I used [ResponseType(typeof(SomeClass))] from System.Web.Http.Description successfully with .NET 4.6.1.
